[hpsdr] ADC Overload

[wully]

Hi Kjell

Thank you for your information. I don't standardwise use PowerSDR since 
I have written my own TRX-Software to learn how DSP ist working. But I 
am using ALEX and have thought, that ALEX is fully controlled by FPGA, 
if you don't influence it by Software on the PC. I have earlier 
constructed an antenna switch for two Mercuries (in Diversity 
experiments) and one Penelope. But since I have put ALEX in, I have not 
used my antenna switch anymore. I will try my antenna swich in addition 
to the ALEX and then, things should be better, since then two switches 
are in series, reducing the possible RF coupling.

73, Alfred
